HUMIDIFIER FOR HEATERS.

To all whom it may concern:

Be it known that I, WLADYSLAW P. KLO- BUKOWSKI, a subject ofthe Emperorof Russia, and a resident of the city of Warsaw, Poland, Russia, haveinvented certain Improvements in Humidifiers for Heaters, of which thefollowing isa specification.

The object of my invention is to provide a heater of .the generalcharacter of that shown in my application No. 570,801, filed July 7,1910 with improved means for supplying moisture to the heated air, indirect proportion to the quantity and temperature of said air; thearrangement of parts being relatively compact as well as substantial inconstruction; These objects and other advantageous ends I secure ashereinafter set forth, reference being had to the accompanying drawing,in which r Figure 1, is a vertical section illustrating the preferredarrangement and construction of my humidifier as applied inside thecasing of a hot air furnace; Fig. 2, is a horizontal partial section,part of which is taken on the line aa, and part on the line bb of Fig.1; Fig. 3, is a plan ofa portion of the humidifier shown in Fig. 1,without the porous body; Fig. 4, is a fragmentary vertical section of aportion of the preferred form of humidifier employed as part of myheater; Fig. 5, is a section similar to Fig. f but illustrating a partof the adjusting mech anism associated therewith; Fig. 6, is asideelevation of the upper part of my humidifier; and, Fig. 7 is a planof a part of my humidifier, the porous body and part of the watercontainer being omitted.

In order to supply moisture the air in sufficient amounts te sec'ure thebest hygienic conditional provide a sectional annular humidifierpreferably mounted upon a suitable supporting structure and immediatelyadjacent to the fire pot 33 of the furnace. As shown in Figs. 1 and 2,said humidifier preferably consists of a narrow, relatively deep,annular container 3 surrounding and immediately adjacent the fire pot,and

formed with its outer wall less in height than its inner wall.Surrounding'this container is a series ofconcentric steps 4, 5, etc.,arranged in cascade form and having through them a number of openings6for the passage of air. This container is so formed as to be capable ofadjustment vertically on the fire pot in order to vary the rate ofevaporation of its contents, though Specification of Letters Patent.Application filed May'lG, 1911. Serial No. 627,499. a

when made in sections itmay be movable horizontally toward and from saidfire pot in order to attain the same end. If desired, the water supplyto the container 8 may be arranged removably and provided with anoverflow to carryofi' the surplus water from the lowermost of the stepswhichis shown as a container. In order to increase the rate ofevaporation of the water from this device, without adjusting it, I maymount in the container 3 an annular bod of fire brick or otherrelatively porous re ractory material 8; preferably forming this in aseries of sections and fianging it outwardly. It is preferablyperforated as shown at 8 and under operating conditions liquid drawn upinto it by capillary action is thoroughly exposed to the action of therising currents of air. Instead of being made in sections, the porousevaporating body may be made in other forms having a relatively greatevaporating surface without departing from my invention. By reason ofthe fact that this humidifying device is mounted around or immediatelyadjacent the fire pot, the liquid within it is heated to an extent or isevaporated at arate in a great degree proportional to the temperature ofthe source of heat, that is, its temperature is dependent on the rate atwhich fuel is burned in the fire pot, so that the amount of liquidevaporated bears a definite relation to the volume of air which isheated. Thus when the heater is driven to its full 'capacity,the airdelivered therefrom is more highly heated and passes through it ingreater quantities than when itis burning less fuel, and the amount ofmoisture supplied to the air by my humidifier is automaticallyregulated,

.being at all times supplied in the desired and necessary vamounts.

\Vhile I have described and illustrated the container constituting themain part of the humidifier as formed in a number of cascades, it isobvious'thatthe angle, and detail arrangement of these may" be variedwithin wide limits without depa'rting from my invention; the object ofwhich is to pro-, vide a water container immediately adjacent the sidesof the fire pot or other source of heat.

The moving of the humidifier in horizon tal or vertical directions maybe accomplished in various ways, and I have illustrated one way ofcarrying out theinvention. The motion in a vertical direction isPatented A r; 1,1913.

obtained by means of the following device: Outside of the casing 2, asmall handwheel 9 is fixed to a shaft 10 which has fixed to its oppositeend a beveled gear 11 meshing with a second beveled gear 12 fixed on theend of a screw shaft 13. On this latter is threaded a nut 14 with arms15 having at their ends vertically extending rods 16 sliding in guides17 These rods 16 are attached to a suitable frame 18 on which thehumidifier is mounted and said frame slides on and is guided by rods 19fixed to the casing 2. Turning the handwheel 9 to the right or left handcauses the humidifier to be raised or lowered relatively to the fire pot33 as may be desired. In order to move the humidifier horizontallytoward or from the fire pot,

there is provided a second handwheel 20' outside of the casing 1, 2 andfixed on a shaft 21. This latter has fixed to its inner end a gear wheel22 meshing with a toothed rack 23 formed on or attached to an annularstructure 24 supported in suitable bearings 25. This structure has teethformed on its inner edge in position to mesh with elongated pinions 27fixed to spindles 28 sliding vertically in guides 29 and having on theirupper ends gears 30. These latter gears each mesh with a toothed bar orrack 32 fixed to the under side of the humidifier sections. By turningthe han'dwheel 20, the

sections of the humidifier will be moved toward or from the fire pot 33,as the case maybe.

From the above description it will be seen that the humidifier may bemoved up or and the handle20. It is also obvious that the porous body 8may be used in connection with the apparatus shown or omitted ifdesired, without departing from my invention.

I claim 1.
